Disney CEO Robert Iger told CNBC on Tuesday that his company didn't shell out $4 billion to buy Lucasfilm to merely put out a new "Stars Wars" movie every other year: Disney is also working on other theatrical properties based on "Star Wars" characters.

Walt Disney has agreed to buy filmmaker George Lucas's Lucasfilm Ltd and the "Star Wars" franchise for $4.05 billion in cash and stock, a blockbuster deal that adds one of the most beloved franchises in entertainment history to Disney's lineup.
